- 外装缶の開口部にガスケットを介して封口缶を装着して当該開口部の周縁部をかしめることにより封口された扁平な丸形の電池容器を有し、
前記電池容器内に、円形の袋状のセパレータ内に収容した正極と負極とを交互に複数段積層してなる積層型の電極体および非水電解液が収容されており、
前記正極は正極集電体の両面に正極活物質層を形成してなるものであって、前記正極集電体から正極リードが前記電極体の一側方に向けて延びて前記セパレータから導出されており、
前記負極は負極集電体に負極活物質層を形成してなるものであって、前記負極集電体から負極リードが前記電極体の他側方に向けて延びており、
前記袋状のセパレータは、該セパレータの材料である二枚のフィルムで前記正極を挟んで重ね合わせ、それらフィルムの周縁部を互いに接着することで形成されており、
前記袋状のセパレータの周縁部には、前記負極リードの対向位置を除く位置に、前記袋状のセパレータ内の空気を排出するための二個ないし五個の非接着部が分散状に設けられていることを特徴とするコイン形二次電池。 - 前記非接着部のうちの一個は、前記正極リードを前記セパレータ外へ導出させるための導出部が兼ねている請求項1記載のコイン形二次電池。
- 前記電極体の外周には、結束テープが前記正極リードおよび前記負極リードの延びる方向と直交する方向に巻き付けられており、
前記非接着部は、前記袋状のセパレータの周縁部において前記結束テープの配置位置を除く位置に設けてある請求項1又は2記載のコイン形二次電池。
